+This directory contains kernel headers that must be modified by hand
+before they are used to generate Bionic's "cleaned-up" user-land headers.
+
+Currently this includes scsi/scsi.h from 3.18, which mixes userspace-facing
+and kernel-facing definitions even after the uapi cleanup.
+
+They are mostly covered by the GPLv2 + exception, and thus cannot be
+distributed as part of the platform itself.
+(NOTE: The cleaned up headers do not contain copyrightable information and are
+distributed with Bionic)
+
+Importing modified kernel headers files is done using scripts found in bionic.
+
+For more details, please read bionic/libc/kernel/README.TXT.

 Importing modified kernel headers files is done using scripts found in bionic.
 
 For more details, please read bionic/libc/kernel/README.TXT.
+
+Generated Headers
+-----------------
+The uapi directory contains uapi version of original kernel headers that are
+used to generate Bionic's "cleaned-up" user-land headers. The script
+bionic/libc/kernel/tools/generate_uapi_headers.sh automatically imports the
+headers from an android kernel repository.
+
+Running the script:
+
+generate_uapi_headers.sh --download-kernel
+
+In order to run the script, you must have properly initialized the build
+environment using the lunch command. The script will automatically retrieve
+an android kernel, generate all include files, and then copy the headers to
+this directory.
+
+The headers are mostly covered by the GPLv2 + exception, and thus cannot be
+distributed as part of the platform itself.
+(NOTE: The cleaned up headers do not contain copyrightable information and
+are distributed with Bionic)
+
+For more details, please read bionic/libc/kernel/README.TXT
+
+Manually Modified Headers
+-------------------------
+The scsi directory contains a set of manually updated headers. The scsi kernel
+header were never properly made to into uapi versions, so this directory
+contains the unmodified scsi headers that are imported into bionic. The
+generation script will indicate if these files have changed and require
+another manual update.
+
+The files from the scsi directory will be copied into bionic after being
+processed as is, unless there exists a file of the same name in
+../modified/scsi. Any files found in the modified directory completely
+replace the ones in the scsi directory.

-This directory contains the uapi version of original kernel headers that are
-used to generate Bionic's "cleaned-up" user-land headers. The script
-bionic/libc/kernel/tools/generate_uapi_headers.sh automatically imports the
-headers from an android kernel repository.
-
-Running the script:
-
-generate_uapi_headers.sh --download-kernel
-
-In order to run the script, you must have properly initialized the build
-environment using the lunch command. The script will automatically retrieve
-an android kernel, generate all include files, and then copy the headers to
-this directory.
-
-The headers are mostly covered by the GPLv2 + exception, and thus cannot be
-distributed as part of the platform itself.
-(NOTE: The cleaned up headers do not contain copyrightable information and
-are distributed with Bionic)
-
-For more details, please read bionic/libc/kernel/README.TXT
